Radiological Training for Accelerator Facilities
TYPES OF CONTROLS
EO-12 DESCRIBE each access mode at the facility and access to beam and beam containment
including interlocks and warning devices and systems.*
Many types of controls are used at accelerator facilities to protect personnel from exposure to
ionizing radiation and other hazards such as:
The design of an effective safety program incorporates a combination of engineered and
administrative controls and personnel protective equipment, (e.g., respirators, protective clothing
etc). However, per 10 CFR 835.1001(a) the primary methods used shall be physical design
features. Administrative controls and procedural requirements shall be employed only as
supplemental methods to control radiation exposure.
The following sections describe the various controls encountered at accelerator facilities that are
designed to protect personnel from ionizing radiation.
EO-11 IDENTIFY engineered and administration controls (Facility Specific)
Equipment designed to protect personnel from a hazard by preventing entry to accelerator
enclosures, providing a warning of impending beam, or means to shield out or remove the source
of the hazard. Engineered controls may be active or passive.
